Illumination of switches 1 (PWM1): Shortcut to ground
â–¶ How to fix
1. Remove some of the consumers from the harness. 2. Check the harness.
What you'll see
No driver-visible symptom recorded.
System reaction
PWM1 is turned off. It could be turned on after switching wakeup1 off/on, when fault is fixed.
Diagnostic depth
Detection
The feedback for the load for PWM1 is indicating short circuit to GND Only stored when ignition is ON.
Possible cause
1. The harness is shorted to ground 2. Too many consumers (i.e.LEDs) are connected to the harness.
